"A simple job just using Gustav's effect" Deck 2013

Playing

It's a simple task that uses Gustav Max's effect four times. (Don't say you can't use it 4 times)
People tend to think that Gustav has no use other than Old Sacred Time or Mecha Phantom Beast, but you can make a Gustav Deck!
Basic movement
Use Metaion, Reflect Slime, sin Cyber End, Sphinx, Trago, Reflect Slime, and more to bring out Gustav.
When Gustav is sent out and Gustav goes to his GY, he uses Exodios to retrieve Gustav from GY and Xyz with Mirror Ladybug etc. Gustav...
You can collect Gustav and Exodios with Exodios, so Gustav can appear virtually infinitely!
…everyone! "If you want Gustav, let's make a Mecha Phantom Beast!"

Strength

Exodios, Gustav from Mirror Ladybug is very strong.
Also, Exodios is normally excluded, but since it becomes Gustav's Xyz material, it falls into GY.
If Exodios falls on GY, you can collect it again with Exodius, so Gustav will appear infinitely!
picture? "Will it end before you can use the effect 4 times?" "I can't hear you... (sweat)

Weakness

After all, I can't compete with the one-kill that's popular these days...
Christia, Opion is not a threat because Metaion can handle it somehow...
… Oh, please don't do Jougen x Goethe, I'll die.
